CAR-WH EEL.

SPECIFICATION forming part of Letters Patent No. 311,837, dated February3, 1885.

Application tiled February 16, 1884. (No model.)

To all whom it may concern..-

Beit known that I, WILLIAM JosLIN, a citizen of the United States,residing at Iainesville, county of Lake, and State of Oh-io, haveinvented certain new and useful Improvementsin Vheels; and I do herebydeclare the following to be a description ofthe same, and of the mannerof constructing and using the invention, in suoli full, clear, concise,and exact terms as to enable any person skilled in the art to which itappertains to construct and use the same, reference being had to theaccompanying drawings, forming a part of the specification, theprinciple of the invention being herein explained, and the best mode inwhich I have contemplated applying that principle so as to distinguishit from other inventions. i

The object ot' this invention is to provide a wheel in which therelative construction and adjustment ot' tire and wheel-body furnishready means for remedying any occurring looseness of the tire.A

- Figure l is a diametric section of a Icarwheel, illustrating theprinciple of my invention. Fig. 2 is an outer side elevation thereof,with the face-plate removed.

A is the hub, B the wheel-body, andb the braces. The tire C is madeindependently ot' the wheelbody, and is provided on its inner peripherywith the annular flange c. The portion d of the inner periphery ofthetire is formed as a bevel, inclining outwardly from the flange c. Thecircumference of the wheelbody is formed as a counterpart bevel, e,inclining in cross-line at the same angle as the tire-bevel. Bolts fseverally pass at different points through the marginal portions,respectively, of the wheel-body and face-plate D, and also through thesaid tire-iiange. Thejoining surfaces oi' wheel-body and tire are thusunited in counterpart wedge shape, and the relative diameters of thewheel-body and the inner periphery of the tire are such that theWheelbody can be adjusted nearer to the said ange, as occasion mayrequire, for the tightening of the tire, the diameter of said wheel-bodybeing of greater dimension in the plane of 'its face next to said dangethan is the diameter of the tire-incline at the point of its immediatejunction with said flange, said difference insaid diameters creating anopen space between said wheel-body and said flange, thereby providingroom for the adjustment aforesaid, which spreads the tire radiallyoutwardly.

In litting the parts together, as the wheel is set up a comparativelysliglt pressure suffices to wedge the wheel-body within the tire andrender the wheel iirm. The angle of inclina- 6o tion of thebevel-surfaces mentioned may be ot' any desired degree.

By the adjustable mechanism thus described the well-known tendency ofcar-wheels to become loose and shaky is adequately provided against.Face-plate D serves to bind the portions of the tire together in case ofthe latters fracture.

Vhat, therefore, I claim is- A car-wheel consisting in the combination,with the tire C, provided with the flange c and the incline d, of thewheelloody B, having greater diameter in the plane of its face next tosaid iiange than is the diameter of that portion of said tire-incline atits immediate junction with said flange, said difference of saiddiameters normally creating an open space between said wheel-bod y andsaid flange, the joining faces d and e ofsaid tire and wheelbody beingcounterpart inclines to each other, and bolts f, 'connecting togethersaid flange and wheel-body, said parts being adapted to permit thedrawing of the wheel-body by said bolts in lateral wedge movement towardsaid flange, thereby spreading the tire radially outwardly, by whichoperation any looseness ot' the tire is remedied, substantially as setforth. Y

In testimony that I claim the foregoing to be my invention I havehereunto set my hand 9c this 13th day of February, A. D. 1884.

WILLIAM JOSLIN.
